= Cycling, Incremental, Compressed, Encrypted Backups to Amazon S3 =

 * Dead-simple configuration
 * Automatic rotation of backup sets
 * Optional decaying backup schedule (thanks to Scott Squires)
 * Alternation of full and incremental backups (using "tar -g")
 * Integrated GPG encryption
 * No temporary files used anywhere, only pipes and TCP streams (optionally, uses smallish temp files to save memory)
 * Integrated handling of MySQL dumps
 * Integrated handling of PostgreSQL dumps (thanks to Scott Squires)
 * Integrated handling of Subversion repositories, and of directories containing multiple Subversion repositories (including incremental backups-- thanks to Kevin Ross).

s3napback is basically a convenience wrapper around [http://js3tream.sourceforge.net/ js3tream], and is at least partly inspired by the [http://www.perusion.com/misc/Snapback2/ snapback2] script (which is still a great solution for incremental rsync-based backups to your own disks).
